The makefiles have been written to support Microsoft Visual C++.  I am
using MSVC2.0, but the options should hopefully be the same for other
versions.  Compiler options will vary between compilers.

1. Before starting a build, you need to set your 'lib' environment
   variable appropriately.  For a debug build, it should include
   $BASEDIR/tcl73/Debug $BASEDIR/winio/Debug $BASEDIR/xlib/Debug
   $BASEDIR/tk36/Debug.  For a release build, the 'Debug' in the
   above directories should be replaced with 'Release'.  BASEDIR
   refers to the directory in which this file resides.

2. There are two configurations supported: Debug and Release.
   For a debug build, just use 'nmake'.
   For an optimized build, use 'nmake CFG=Release'

3. Running
   a. Set the environment variables TCL_LIBRARY and TK_LIBRARY
      to point to where the library files are.  They should be
      in .../lib/tcl and .../lib/tk.  If you do not set them,
      /usr/local/lib/tk and /usr/local/lib/tcl are checked by default.

   b. Your path needs to include the DLLs.  Add $BASEDIR/tcl73/Debug,
      $BASEDIR/winio/Debug $BASEDIR/xlib/Debug $BASEDIR/tk36/Debug to 
      you path.  For a release build, the 'Debug' in the above directories
      should be replaced with 'Release'.

   c. To run wish, it should be in ./debug/wish.exe
      To run tclsh, it should be in ./debug/tclsh.exe
      (Replace debug with release for a release build).

4. Notes
   Three executables and three DLLs are built:
      tclsh.exe:    Tcl shell with no graphics support.
      wish.exe:     Wish
      tclspawn.exe: Utility for launching subprocesses.

      tcl73.dll:    Tcl library
      tk36.dll:     Tk library
      lxlib.dll:    Xlib compatability library
